Presentation Summary

Real-time and continuous monitoring of physiological signals is essential for mobile health (m-Health), which is becoming a popular tool for efficient and convenient medical services. In this talk, an active pulse sensing system that can detect the weak vibration patterns of the human radial artery is constructed with a sandwich-structure piezoelectret/cellular polypropylene (PP) piezoelectret that have high piezoelectricity. The high precision and stability of the system result in possible medical assessment applications, including the capability to identify common heart problems (such as arrhythmia) or diagnose health conditions; the feasibility to conduct pulse palpation measurements similar to well-trained doctors in Traditional Chinese Medicine; and the possibility to measure and read blood pressure.
